Abstract
To heat articles in the vacuum container as uniformly as possible by bombarding them with electrons from a low voltage arc discharge, the plasma flame is not directed at the articles as hitherto usual, but caused to extend past the articles to be heated, by providing a magnetic field in which the lines of magnetic force favoring the propagation of the plasma extend in a direction skirting the surfaces of the articles. Preferably, a magnetic field is provided which is parallel to the axis of the plasma flame, and the articles to be heated are arranged cylindrically around the flame.
